nvidia-drm-arm-cflags.patch

Description: Add -Wa,-mimplicit-it=thumb to CFLAGS if building on ARM
 The build of the nvidia-drm kernel module fails on kernel 4.5+ on armhf. The
 following error is reported:
   /tmp/ccy8zHSc.s: Assembler messages:
   /tmp/ccy8zHSc.s:97: Error: thumb conditional instruction should be in IT
     block -- `movne r0,#1'
 As a workaround, add -Wa,-mimplicit-it=thumb to the CFLAGS if building on arm.
